Well, if there really is no minimum thickness, then I'm fine with running
the same rotors. I guess I ran a little too long on the pads, as the
annular ring of which you speak, located on the outer diameter of the rotor,
is more or less gone. I finally noticed the metal to metal sound yesterday
while driving with the window open, otherwise, wasn't too loud. Luckily,
only a portion of the pad backing made contact...the pad obviously didn't
wear completely true. One corner is slightly more worn than another.
If I find that the rotor needs replacing, at least now I know where to go.
I'm just not ready to shell out a ton of money on rotors for a car with such
